Sun Hydraulics Pressure Reducing Valve | SCCA XECA XBCA | 3-Port Reducing/Relieving

Sun Hydraulics Pressure Reducing/Relieving Cartridge Valves

Product Overview: Sun Hydraulics Pressure Reducing/Relieving Valves are essential for precise pressure management in advanced hydraulic circuits. These 3-port valves reduce a high primary pressure to a consistent, lower secondary pressure. Uniquely, they include an integrated Relieving function, which vents secondary circuit pressure to the tank if it exceeds the setting due to external loads. This category features high-precision models: SCCALAN, XECAXXN, XBCAXXN, XZCAXXN, and XCOAXXN.

Designed as screw-in cartridges, these valves offer rapid response, minimal hysteresis, and extreme reliability. They are the premier choice for pilot control systems in construction machinery, industrial press pressure staging, machine tool fixture circuits, and any hydraulic branch requiring constant pressure output.

Key Technical Advantages:

• 3-Port Integrated Logic: Combines reducing and relieving functions in a single cartridge, simplifying manifold design and reducing space requirements.

• Superior Regulation Linearity: Precision-ground spools ensure smooth adjustment and stable pressure with minimal fluctuation.

• All-Steel Durability: All internal working components are hardened for maximum wear resistance under continuous high-pressure cycles.

• Series Precision Matrix:

  • SCCA Series: Direct-acting design for ultra-fast response, ideal for low-flow, high-dynamic applications.

  • XECA/XBCA Series: Pilot-operated architecture supporting precise pressure control at higher flow rates.

  • XZCA/XCOA Series: Optimized for specific cavities and flow requirements, providing flexible system integration.
